# AttributeScopes

Collections of attributes that system frameworks define.

## Declaration

```swift
@frozen enum AttributeScopes
```

## Overview

Overview Attribute scopes define groups of attributes appropriate for use with attributed strings in a certain domain. Attribute definitions contain a name, value type, and encode/decode methods to support serialization. For example, the AttributeScopes.FoundationAttributes scope provides an attribute type for a link to a URL, AttributeScopes.FoundationAttributes.LinkAttribute, along with a property to access this type, link. Because AttributeScopes.FoundationAttributes implements AttributeDynamicLookup, you can access the link attribute by name, as this example shows: var attrStr = AttributedString("Example site") attrStr.link = URL(string: "http://example.com")
